Sydney Warned As Infectious Disease Is Spread Through City

A measles diagnosis has sparked fears that the infection may have been spread through Sydney, prompting health officials to issue a warning to local residents.

The patient has recorded visits to a shopping centre and two restaurants and reportedly travelled on two trains in the city's eastern suburbs between September 5 and 11.

South Eastern Sydney Local Health District are urging people to be wary of contracting the disease, especially if they also visited the same areas.

"The measles virus is highly contagious and is spread through the air by someone who is unwell with the disease," Public Health Director Professor Mark Ferson said.

"People with measles symptoms should stay home from school or work and not go out in public."

Symptoms of the disease include fever, sore eyes and a cough which may be followed by a rash a few days later.

"We recommend medical attention be sought, but if you or your child shows these symptoms you should call the doctor's surgery before you go in so they can make arrangements to see you without the risk of you spreading the virus to other people," Professor Fearson added.
